sold my power tap for a disk wheel - Page 2

Junker,

You are burning Mental Matches...

Jim

There is no generic answer to your question. It turns on three issues, all of which are specific to you and your equipment and your course. First, how good are you at managing your power at and near your FTP? Can you put a piece of masking tape over the watts display of your PT and ride within a couple of watts of your target power for an hour? Or, do you (like most of us) start out too hard and then have to back off in the 2nd half, resulting in a fairly large difference between AP and NP? Second, what is the course (grades and normal wind conditions)? If the course has numerous grade and wind changes, it argues for a variable power pacing strategy (which is much more difficult to manage without a PM). Third, what is the drag difference between the wheels you are considering? There are test data available on most wheels at biketechreview.com. In the end, it comes down to a set of computations and a probability distribution of predicted outcomes (with all due respect to those who think it comes down to attitude, sweat in the eyes, burning in the lungs and all that "You can do it if you think you can do it!" stuff). I advocate making cold, unemotional decisions about equipment and strategy, then going out and executing the strategy. Anyway, there's always the last 5 mins when you have the finish line in sight to ride your guts out, cross the line and pass out.

But whatever you do, don't make equipment changes at the last minute before a big event!

Just in case you didn't have enough things to worry about before now...

59:24 i used the disk because it was raining, i did not want to get the powertap wet especially since it wasnt mine.

i have a chance to do another one next week

Fantastic.

What was your AP/NP?

If you track CTL/ATL/TSB, how did the day look for you?

Jim

Wow, 270w got you a 56:30! Nice. Was it a full 40k TT?

I was thinking the same thing...then I looked up his FTP.

65 kg and his back is probably flat as a board...

OJ, make sure you update your FTP listing...

Awesome Job...

If you are using WKO+, you would know the other acronyms...

Jim

my download was 300 metres short 39.73 , i want to shoot for 300 watts next year hopefully same course
